To determine the unit rate of the proportional relationship from the given data points on the graph, we can analyze the provided coordinates.
The data points you provided are:
- (30, 3.00)
- (15, 1.50)
- (8, 0.55)
- (0, 0)
The first number in each pair represents the ounces, and the second number represents the cost in dollars.
To find the cost per ounce, we can divide the cost by the number of ounces for one of the points:
Using the point (30, 3.00): \[ \text{Cost per ounce} = \frac{3.00}{30} = 0.10 \]
Using the point (15, 1.50): \[ \text{Cost per ounce} = \frac{1.50}{15} = 0.10 \]
Using the point (8, 0.55): \[ \text{Cost per ounce} = \frac{0.55}{8} \approx 0.06875 \quad (\text{not a unit rate based on other data}) \]
From the calculations, we can see for both (30, 3.00) and (15, 1.50), the unit rate is $0.10 per ounce.
Thus, the correct answer is: A. Canned peas cost $0.10 per ounce.
